The source also said that the Navy was doing its best to trace the two missing officers.Meanwhile, the condition of the injured personnel, who had inhaled smoke and were airlifted to the naval hospital INS Ashwini, is reported to be stable.

Hours after the mishap and in the wake of a spate of accidents involving the Naval warships in the recent past, Navy Chief Admiral D K Joshi had resigned on Wednesday taking moral responsibility.
